The climb from the waterfront tells you a lot
If you want to know how your transmission is doing, pay attention on the way up from the ferry dock. A healthy transmission holds a gear and pulls. One that’s low on fluid or wearing out will hunt between gears, slip, or let the engine race without the car gaining speed.
Those are early warnings. Caught now, the repair is often small.
If you tow, read this
Plenty of Mukilteo trucks and SUVs pull a boat. Towing makes heat, and heat is what destroys transmission fluid. Add a steep launch ramp and you have the toughest job a transmission ever gets.
If you tow, your fluid is due sooner than the normal schedule, and the transfer case and differentials need their fluid changed too. We service all of them, and we work on trucks every day. See differential service and diesel and truck repair.
